method has been developed for the preparation of oxazolo-[5,4-b]pyridin-2(1H)-ones based on the Hoffmann reaction of 2-oxo-1,2-dihydropyridine-3-carboxamides. Hydrolysis of oxazolo[5,4-b]pyridin-2(1H)-ones and the Hoffmann reaction of 2-oxo-1,2-dihydropyridine-3-carboxamides yielded 3-aminopyridin-2(1H)-ones, including 4-aryl substituted derivatives in the series, for which effective phosphors with a
基于2-氧-1,2-二氢吡啶-3-羧酰胺的霍夫曼反应,已经开发了一种制备恶唑-[5,4 - b ]吡啶-2-2 (1 H)-的方法。恶唑并[5,4 - b ]吡啶-2(1 H)-one的水解和2-氧-1,2-二氢吡啶-3-羧酰胺的霍夫曼反应产生3-氨基吡啶-2(1 H)-one,包括该系列中的4-芳基取代衍生物,其有效荧光粉的量子产率高达0.78。通过紫外和发光光谱法研究了3-氨基吡啶-2(1 H)-1的光物理性质,揭示了其结构与光物理性质之间的关系。
